PROTECTOR AND GUIDE.

Application filed May 21, 1915.

To all whom t may concern.

Be it known that I, MORRIS P. WILLIAMS, a citizen of the United States, and a resident of Gilbertville, in the county of Worcester and State of Massachusetts, have invented a new and Improved Protector and Guide, of which the following is a full, clear, and exact description.

The invention relates to twisting frames, and other Similar textile machinery, and its object is to provide a new and improved protector and guide arranged to prevent adjacent threads from becoming entangled in case one breaks, to insure proper twisting of the threads without danger of the threads dropping under the roller on stopping the machine, and to enable the operator to quickly and correctly pass the thread around the roller and into the guide at one operation.

In order to accomplish the desired result, use is made of a channel for the passage of the thread, the channel being provided at its upper end with a vertical elongated thread guide and means to one side of the channel for guiding a thread into the said thread guide and channel, the upper end of the protector and guide being adjacent to one side of the usual roller around which the thread passes after leaving the traverse. t

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a cross section of a portion of a twisting frame provided with the protector and guide; F ig.2 is an enlarged side eleva* tion of the protector and guide with part broken out; Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2; Fig. et is an inverted plan view of the same; Fig. 5 is a sectional elevation of the same on the line 5 5 of Fig. 6; Fig. 6 is a plan view of the same; Fig. 7 is an enlarged side elevation of the head of the protector and guide; Fig. 8 is a perspective view of the tail end of the protector and guide with part broken out; Fig. 9 is a cross section of the same on the line 9--9 of Fig. 8; and Fig. 10 is a cross section of the protector and guide on the line 10-10 of Fig. 7.

As shown in Fig. 1, the two threads A, A to be twisted together unwind from the bobbin B and then pass through the eye C of the traverse D mounted to travel up and down Specification of Letters Patent.

in the usual manner on the main frame E of the machine. The double thread A after leaving the eye C passes around the vertically disposed roller F and then enters and passes through the protector and guide G to finally pass through an eye II down to the twisting spindle (not shown).

The protector and guide G is supported in the inclined position on a double bracket I attached to the main frame E, as plainly shown in Fig. l. The protector and guide G 1n its general construction is formed of a single piece of metal of approximately U shape in cross section (see Fig. 3), thus providing side members G, G2 and a rounded off bottom G3 so that a channel is formed Jfor the passage of the double thread A, as indicated in Figs. l and 5. The upper end of the said member G2 is provided with a flange J hanging downward over the upper end of the other side member G and `:being spaced therefrom. The side member G is provided at its upper end with an extension K, over the top portion of which the flange .I extends, as will be readily understood by comparison of Figs. 2 and 7. 'Ihe upper edge of the side member G2 has an approximately vertical portion G4 (see Fig. 7 and an upwardly and rearwardly inclined portion G, and on the inner faces of the said portions G4L and G5 is arranged a thread guide L, preferably made of a piece of wire, following the edge portion Gt, G5 and being provided at the bottom with an upwardly extending hook L and at its upper end with a downwardly extending hook L2, and this hook portion extends into a recess J formed in the inner face of a flange J. 'Ihe free end of the hook L its into a recess K formed at the junction of the extension K with the side member G.

The inner face of the extension K is disposed in close proximity to the peripheral face of the roller F so that the double thread A after leaving the roller F readily passes through the thread guide L into the channel formed by the side members G G2 and the bottom G3. In order to prevent the lower portion of the thread in the channel from accidentally moving out of the same, use is made of a retaining lug N arranged on the inner face of the side member G2 near the lower end thereof, as plainly indicated in Figs. 6 and 9. The portion G of the side member G opposite the lug N is bent outward and recessed to form sufficient space between the face of the lug N and the said portion GC to allow the thread to pass downward under the concave bottom N of the lug N. Thus the lng N prevents the thread from accidental upward movement out of the channel. y n

In case a thread is broken and it is desired to place the same aroundthe roller F and into the protector and thread guide G,

then it is only necessary for the operator to pass the threads under the fiange J and draw them up for the threads to pass between the iange J and the extension K and the upper portion of the sidemember G and into the channel to extend within the'thread guide L. The threads .are then passed in the usual manner through the eye C mounted on the traverse I) at the rear of the roller. The threads are then looped up over and around the roller F. The threads are now passed through the eye II mounted at the end of the trip lever, then to the twisting spindle, the operator having gone through practically the same movements in y the usual manner .as though the protector and guide was noty there. As soon as the threads get the pull from the spindle they readily find their own way into the channel and down 'under the retaining lug arranged on the innen face of the side member G2- near the lower end thereof, cated in Figs. 6 and 9.

N lis used to prevent the loose threads from blowing out of channel caused by the draft from spindle. Should it be necessary this same lug can be used to give more pressure on the trip lever H by mounting the protector and guide on the machine with the lower end tilted down more. Should the operator place the threads around the roller then the threads are also accidentally placed around the top of the protector `at the same time. The shape of the protector is Vsuch that as soon as. the roller starts in motion it lifts the threads up and over the top of the protector into their proper position on roller. without causing any irregular twist. The overhan'ging flange J extends down low enough to prevent the threads from being caught under same when thethreads are accidentally thrown over the top of protector.

The double bracket I consists of two plates I', I2, of which the plate I overlies the outer face of the side member G, and the other plate I2 overlies the outer face of the side member G2. The plate I2 is provided near its lower end with a pin I3 engaging an aperture in the side member G2,

as plainly indiand the upper end of the said plate I2 isV likewise provided with a pin I4 engaging an aperture in the side member G2. The plates I and I2 areprovided with overlying angular lugs I5, I6 fastened tothe main frame E by bolts or other fastening protector and The retaining lug means. By the arrangement described the guide can be readily passed betweenl the bracket plates-I and I2 and engaged with the pins I3, IA1 to hold the protector and guide in position on the bracket. It is understood that the pins I3, IH1 can be readily swung into place.

It will be noticed that when the twisting frame is running the double thread A is free to move up and down in the elongated guide L to correspond with the up and down movement of the traverse I). protector and guide G extends from between two rollers F to and between adjacent separating boards O for the spindles, it is evident that a broken thread is confined in the guide .and is not liable to become entangled with an adjacent thread. The bottom hook L of the guide L is a distance above the bottom of the roller F and hence the thread on the .roller F is held up and is not liable to drop to the bottom thereof on stopping the machine. the double bracket I the protector and guide may be readily placed in correct position on the machine or removed therefrom whenever it is desired to do so.

Having thus described my claim as new Patent:
